Abstract
Abstract Deciding on an aeration system technical characteristicssuch as energy efficiency of oxygen transport in refinery waste water and capacity of oxygen introduction is an important question. With the same membrane air distributor, in the same examined range of waste motor oil contents 5 and 10 gm−3 and air flows 2, 6 and 10 m3 h−1 energy efficiency of oxygen transport is better up to 54% and twice the real capacity of oxygen introduction, in the water column 2 m high, compared to water column 1 m high. The improvement of technical characteristics is achieved in the aeration regimes with the longer retention time between air input and output and minimal electrons density in the gas bubbles. In our paper it is proposed, electrons flux controls the oxygen transport volumetric coefficient, which determines the technical characteristics of aeration system.
